. "This invention relates to the manufacture of molded counter stiifeners, more commonly called counters.

- A counter usually is made of fibre board or leather andincludes a main body shaped to fit around the sides and back of the heel and an inturned flange which lies under the bottom of the heel. The usual commercial counter molding machines include a center. mold similar in shape to the heel portion of a shoe last and side molds movable toward and from the center mold and cooperating with itto shape the main body of the counter. lVhile the counter is gripped between and being shaped by these molds, a wiperslides down over the front face of the center mold and turns o erthe flange and irons it down.

' There is considerable tendency for the flange to spring back after it has been released from the molds and thus to change its relationship to the main body of the counter. This impairs to some degree the fit of the counter on the shoe lastand is objectionable for this reason. Attempts to overcome this difiiculty by applying additional pressure on the wiper are only partially successful and the increased pressure tends to cause the wiper to shear the flange off the main body of the counter and thus to ruin it.

' The present invention deals especially with this problem and aims to devise a simpleand thoroughly satisfactory solution for it.

The nature of t 1e invention will be readily understood from the following description I when read in connection with the accompanying drawings, and the novel features will be particularly pointed out in the appended claims.

In thedrawings,

For purposes of disclosure the 'inventionhas been illustrated as applied to'thecountertmolding machine shown and described in my prior ae- Patent No. 1,332,259. This machine, in coni men with 7 other 1 counter molding machines, such as the Stewart and Young machines, includesa center mold 2 and two 'coo perab ing side molds 3-3, F ig."3. The sidefmolds B5 are arranged to swing laterallytoward and from the center mold, and the latter mold has bothan up and down movement rel'a tively to the side molds, and also .a movement backward and forward into and out of the 76 plane of the side molds in order to'faci-litate the removal of the molded counter from the center mold. 111 the machine shown in 'the patent above designated guide pieces't are secured to the frame: of the machine at the T5 front thereof and cooperate with the frame to form vertical guideways in whichthe wip er slides. The sliding movement is given to the wiper by a cam operated mechanism in eluding a lever 5, Fig. l, and a link 6. For a more complete understanding of the general organization the machine and the features just mentioned, reference should be made'to my prior patent above designated. When the counter blank is brought totlie counter molding machine it is slightly damp; orin temper, the preliminary shapingop erations-have been performed on it, and usually it has been rolled. This rollingopeb ation .concaves the counter blank and corru gates the margin which later will be'tu'rne'd over to form the flange. The blank 50' prepared is bent into ahorseshoe' shape and placed between the center and-"side molds while they are open,-.the margin of the blank" which isto be turned over to form theflangebeing left projecting in frontbfthe faces of the molds. The molds thencl ose, thusf gripping the-blank securely and shaping'ifl,

' and while theblank is so held the'wiper slidesdown over the front faces of the molds and turns over the flange.

The mechanism provided by this invention comprises not only a wiper for turning over the flange and ironing it down, but also additional means, consisting of a roller, for pressing the flange firmly against the front face of the center mold. In the machine shown the usual wiper plate is replaced by a slide 7 having gears or lugs 8+8 integral with it and to which the link 6 of the usual inechaslide thus has, roughly speaking, a U-shape.

1 of the slide 37 A wiper 14 is set into a recess formed in the inner or rearward side of the-slide 10, as

, clearly shown in Fig. 5. In order to adjust the Wiper relatively to the slide 10, three thrust screws 15 are threaded through the horizontal part of the slide'and bear against the wiper 14, while two bolts 1616, which extend loosely through the slide 10, are

threaded into the wiper and serve to draw I it against the inner ends of the thrust screws or bolts 15. This arrangement permits an accurate adjustment'of the inner face of the Wiper relatively to the outer or front face of the center mold 2. V

The wiper acts on the projecting margin or flange a, Figs. 2 and 3, of the counter just as do the wipers in the ordinary counter molding machines, serving to turn the flange over upon the outer face of the center mold and iron it against said face. In the construction shown, however, the wiper 14 is much shorter than in the ordinary counter molding machine.

The roll 18 which also acts on the flange of the counter is provided with gudgeon or axle members rotatably mounted in two parallel arms 1919 both pivoted to the upper end at 20.20, Fig. 3. The slide 7 is slotted, as shown at 21, to receive the roll. In order to adjust the pressure exerted by the roll on the flange, bolts .30 extend through the lower ends of the arms 19-19 i and are threaded into the slide 7 so that by.

turning them'in or out the roll 18 can be, adjusted toward or from the front face of the center mold 2.

The operation of the mechanism will :be

:clearlyunderstood from the foregoing description. It should be noted that as the slides 7-and 10 are moved downwardly, the Wiper 1 L first comes, in contact with the projecti-ngflange of the counter, turns this flange 5 B a d pr esit against the front face of the center mold 2 exactly as in prior machines, but that this wiper is immediately followed by the'roll 18 which applies additional pressure to the flange, forcing it all the more firmly against the front face of the center mold. Theactio-n of the roll, however, is quite different from that of the wiper since it does not have the rubbing effect which is characteristic of the wiper. Usually the molds are heated, and the wiper also is sometimes heated, as in prior machines, the heat serving to set the fibre more definitelyin the desired shape and to reduce the tendency of the fibre to spring back after the counter is released from the molds.

It should be noted that in this machine the roll 18'and wiper 14: are supported inde' end= ently of each other and are indepen ently adjustable. Consequently, the pressure applied by either of these members to the flange of the counter can be adjustedindependently of the other. This is an important practical advantage. It is entirely feasible, and usually preferable, to use more pressure on the roll 18 than on the wiper 1 1 due to the fact that the roll follows the wiper,'and the'furthe tendency for the flange to spring back is substantially eliminated. This arrangement of the two members which act on the flange so I that their pressure can be independently adjusted is also valuablein cases where these members are of such a nature that they exert substantially the same action on the flange, as well as in those cases where their action is quite different.

The mechanism so far described isdesigned for use in moldingcounters in which the flange is'flat and lies in a single plane. In

themolding of such counters the surface of tie roll 18 is substantially a true cylinder. It rolls freely in its bearings and is revolved by the friction of the material on which it bears. There is some demand, however, for a counter having a depressed or vconcaved flange. In order to mold the flange in this form, the front face of the center mold is recessed or concaved, as indicated in Figs- 6 and 7, where the front face 0 of the mold 2 is so shown. The roll 18 carries a boss 03 which is complemental in cross-sectional form to the face 0 so that after the wiper has turned over the flange in the usual manner, the boss on the roll will then press the turned over flange firmly into the recessed portion this position. I

It will be clear that when a roll of this construction is used-the boss must coincide at each cycle of the machine with the cavity indriven positively. For this purpose a gear 22 is secured fast to the roll and meshes with another gear 23 which runs in contact with a stationary rack 24. The rack is suspended from a bracket 25, Fig. 1, and is held in mesh with thegear 23 by a small bracket 26, Figs.

1 and 5, bolted to one of the arms 19. Suit able adjustment of the rack relatively to the gear 23 is afforded by a shoe or wear piece 27 held in the bracket 26 and backed up by an adjusting screw 28. This machanism kee s the roll properl timed to register with the depression in t e center mold.

The flange of a counter molded by the mechanism shown in Figs. 6 and 7 instead of being flat and lying in a single plane, as in Fig. 2, extends inwardly with reference to said plane. p

The invention provides a mechanism which substantially eliminates the spring back of the flange, and which has the sturdy and rugged characteristics necessary in counter molding machines. It also supplies a single and efficient machine for molding counters with depressed flanges. V 1
